The Science Behind TarCutter

How Does the TarCutter Work?

Why Smoke Cannabis? 

Smoking cannabis is the most popular form of consumption due to its rapid onset and easy dose titration. Both of these premises makes smoking the ideal delivery mechanism for cannabis worldwide, despite some apparent health risks.  There is quite a range of methods to consume cannabis from edibles, vaping, transdermal and inhalation. Nevertheless, to most end-users, smoking is king. 

A comprehensive review of why one should use cannabis is a little beyond the scope of this summary (I mean, you’re here already looking to learn more about our filter, therefore, you already know about the benefits of cannabis), however, Dr. Sulak’s review is a great place to start. Mouhamed et al. also provides an excellent summary.

Given the many health benefits associated with cannabis use, wouldn’t it be nice to have a way to smoke cannabis in an individualized dosing regimen without having to worry about the “tar”, ash and other contaminants that routinely accompany smoking cannabis through a bong?

What is "Tar"?

"Tar” as related to smoking is defined by the Federal Trade Commission (FTC) as well as scientific literature as the total particulate matter minus nicotine and water delivered from commercial cigarettes that are smoked according to a standardized procedure.  

There is something to be noted regarding the similarities of the smoke contents between marijuana and cigarette smoke, namely, that aside from the nicotine content in tobacco smoke and THC content in marijuana smoke, that their smoke profiles are nearly identical.  

Both processes involve burning a leafy material, which produces a host of substances that are known to cause significant harmful health effects. In addition to the same carcinogenic properties, marijuana smoke contains four times the tar of cigarette smoke and the smoking profile/habits of cannabis users fully exposes them to that increased tar content. There is still mixed data regarding the link between marijuana smoke and lung cancer, however, the most recent evidence is concerning.

What is the TarCutter?

The TarCutter is an inline filter made of surgical grade stainless steel and glass that uses activated charcoal along with an engineered flow pattern to significantly reduce the amount of “tar” and other potential contaminants found in marijuana smoke when consumed via a bong.  

Not only does the smoke contain several hazardous chemicals, but the individual smoking pattern itself exacerbates the situation by increasing the amount of lung tissue exposed. We commissioned a study of our filter which demonstrates that, when used in any standard bong, it lowers the exposure to such harmful chemicals by at least 90%.

Enjoy a better smoking experience!
